4 Tug River, McDowell county, West Virginia,

and JosEPHH. GI L, of Newcastle, Lawrence county, Pennsylvania, have invented .a new and useful DoublingApparatum-of which the '1 following is a full,clear,and exactfldescription, reference being had to the. accompanying drawings, forming part of this specification, inwhich..

Figure 1 is'aside elevation of our improved doubler. Fig. 2 is a top .plan view of the same, and Fig. 3 is an end view at the outer end;

Our invention relatesto doublers for doubling sheets or'plates,iand 'i'sidesigned to provide a simple and effective machine which can be set close to the rolls and operated rapidly, so that the doubled sheet may be rerolled without reheating.

In the drawings we show a frame consisting of side frames 2 2, connected at the front end by a table 3, having longitudinal raised ribs 4 4:. Through the rear ends of the side memhers extends shaft 5, to which the tongs 6 6 are connected at opposite ends; Each of these tongs consists of the arm 7, which is rigidly secured to the shaft, and another arm 8, hav ing a hub which loosely surrounds a sleeve 9 around the projecting end of the shaft. The form of these arms is shown in Figs. 1 and 2, the arm 8 having laterally-projecting finger .10. The arm 7 is a short rock-arm provided on the table, and the sheet is drawn by the operator forwardly in the direction of the arrow over these fingers, the sheet resting on.

the ribs. The rear end of the sheet is thus brought over the fingers 10, and the operator then admits motive fluid to a cylinder 16, which operates through loose connection with the rock-arm 17 to rock a shaft 18 and segmental gears 19, secured thereto. These segmental gears intermesh with pinions 20 upon shaft 5,

, and asthe shaft-,5 isrotated-itoperates tozfirst turn the fingers 15 inwardlyanddownwardly to grip the end ofthe sheet. against the fingers 1.0... The furtherrotation of the shaft carries the tongs in the direction of the arrow 5, Fi u 1, thus carrying the rear partof the sheet bodily through a curved path toJthe other end ofthe sheet; :This other end of the sheet restsupon the support and side guides 21, be-.

tween which the operator stands. 'Asthe'sheet is thus doubled theoperator withhis tongs shifts the free.end of the sheet so that it reg-v isters with the end carried overbytheton'gs.

The'operator then releases the tongsand seizes both ends of the doubled sheet and thenshifts the vallve. .:22;'for the cylindern16 1 to exhaust. The fluid-pressure then returns the piston to its normal position and carrying the tongs and operating connections back to the position shown. In the backward movement of the tongs the shaft acts first to turn the fingers 15 back to their vertical position, thus releasing the sheets before the return movement of the tongs. I

To squeeze the doubled sheet, we provide an oscillating platen 23, which is secured to arms 24, pivoted around the shaft 5. A piston-rod 25 of a pivoted motive cylinder 26 has a loose connection with the platen, and the platen when forced upwardly squeezes the doubled portion against the under side of the table, the parts then assuming the position of Fig. 1. The operator after seizing the two ends of the doubled sheet pulls it rearwardly and The advantages of our invention result from the simplicity and compactness of the apparatus, which may be set close to the rolls and operated rapidly. the doubles are preferably drawn twelve inches longer than usual, the extra length When using this doubler,

adding from one to two lengths to the pack, according to the gage. In light gages this will save one part, and in heavy gages it will save two parts, and these heavy gages can be turned over in the doubler and finished in fours at one heat. The free end of the sheet can be easily moved by the operator to-aline it with the end which is gripped and swung over, thus giving a minimum amount of scrap at the irregular end.

Variations may be made in the form and arrangement of the device without departing from our invention.

We claim 1. In doubling apparatus, a pair of jaws, mechanism for swinging the jaws as a whole, one of the jaws being arranged to swing toward and from the other at an angle to the movement of the jaws as a whole, and mechanism for turning the movable jaws; substantially as described.

2. In doubling apparatus, a pair ofv jaws one of which is pivoted in bearings mounted upon the other, mechanism for swinging the jaws as a whole, and mechanism for rocking the movable jaw in a plane at an angle to the movement of the jaws as a whole; substantially as described.

3. In doubling apparatus, a pair of jaws, mechanism for swinging the jaws as a whole, a rock-shaft to which one of the jaws is secured, the other jaw loosely surrounding the said shaft, and mechanism for rocking one of the jaws at an angle to the movement of the jaws as awhole, at the ends of said movement; substantially as described.

4. In doubling apparatus a receiving-doubler having projections, doubler-jaws below the projections, movable doubler jaws arranged to swing down and clamp the sheet upon the lower jaws, and means for swinging the jaws as a whole to double the sheet; substantially as described.

5. A table, a doubling apparatus coacting therewith and arranged to double a sheet, and a squeezing device arranged to be forced upwardly to squeeze the doubled sheet against the lower face under the table; substantially as described.

6. A table, tongs having gripping jaws, mechanism for swinging the jaws as a whole to double a metal sheet, and a squeezer arranged to squeeze the doubled sheet upwardly below the table; substantially as described.

In testimony whereof we have hereunto set our hands.
